Some nice staff but often hear concerns about call buttons unanswered. Dad had to go to SNF Rehab after a bad fall breaking his wrist in 3 places and cardiac stint. Reading reviews and ratings always seem the same, websites make the place look clean and nice. But when he got there it was dated, old furniture, a "gym" with old rehab equipment. And, they crammed at least 2 beds in a room designed for one bed. The nurses were too busy at their med carts and the aides were often disrespectful and uncaring.
As for the call buttons, you'd be surprised how some patients will use the call buttons for things that they could do for themselves, therefore the nurses/aides know which rooms really needed quick attention.
